She would, of course, be Britney Spears, who’s set to guest-star on Jane the Virgin this fall. This certainly isn’t Spears’ first time in front of the camera (more on that later), though there’s a good chance Jane‘s wacky telenovela sensibility – not to mention a potential scene partner in Golden Globe-winning star Gina Rodriguez – will suit the “(You Drive Me) Crazy” singer’s acting style.

Of course, Spears isn’t the only musician who’s struck a chord with a TV gig. From singular cameos (Madonna on Will & Grace) to full-fledged leading roles (LL Cool J on NCIS: LA), many have transitioned from stage to small screen.

Below, we single out some of the best off-the-charts guest appearances.

Courtney Love on EmpireAdmittedly, it wasn’t a huge leap for the Hole rocker and widow of Kurt Cobain to play troubled singer Elle Dallas, but that doesn’t take anything away from the fact that she nailed it. (Love is an Academy Award nominee, after all.) Will Mariah Carey, who’s expected on season 2, make a similarly Glitter-ing guest star?

Katy Perry on How I Met Your MotherSince nobody could seem to remember the name of Zoey’s (Jennifer Morrison) gullible cousin, the HIMYM gang just called her Honey since everything that came out of her moth just wants to make them say, “Oh, Honey!”

Dolly Parton on Hannah MontanaThe country legend was a sweet choice for Miley Stewart’s Mamaw on Hannah Montana – especially during a note-perfect performance of Cyrus’ “True Friend.”

And of course … Britney Spears on Will & GraceEven without Jane the Virgin, Britney has a ton of acting credits. (Let us not speak of Crossroads …) In addition to guest-starring as a receptionist on How I Met Your Mother, she also appeared as Jack’s hilariously Conservative (and surprisingly conniving) assistant Amber-Louise on Will & Grace.
